While there are other options these days for dynamic tracing on Linux like SystemTap, eBPF, KTrace, etc, for those wanting to use DTrace, an Oracle developer has posted a new guide for doing so under Linux...

    I remember seeing some amazing demos of DTrace on some Illumos-derived distro that were pretty awesome. Some of them were basic, but still impressive.

    For example, a guy had a live monitor up of disk latencies or something displaying in a server room, then he went over to some huge array o' disks, yelled at it, and you could see the latencies jump while he was yelling at the disks, showcasing how noise and vibration affect disk I/O performance. It was pretty nifty. Probably not an impressive trick, technically, but still neat.
